To all whom it may concern:

Be it known that I, JAMEs E. CHEEsMAN, a citizen of the United States, and a resident of South Orange, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Apparatus for Treating Lint, of which the following is a specification, reference bein had to the accompanying drawings, formlng a part thereof.

My invention relates to apparatus for treating lint, and particularly means for opcrating upon lint as it is received from a roller cotton gin, to se arate the fibers, and to remove dirt, dust, eafy trash, and the like therefrom.

In a co-pending application serially numbered 604,320 filed January 24:, 1911, I have disclosed and claimed a process for treating lint which consists essentially in moving lint by air currents past a plurality of fingers or similar projections inclined in the direct-ion of the flow of the air currents, and arranged in the path thereof, and in applications serially numbered 604318 and 604,319, also filed on the 24th day of January, 1911, I have disclosed and claimed certain apparatus in which such a process is capable of being carried out.

My present invention relates to an improved form of apparatus therefor in whichthe channel wherethrough the air currents are arranged to pass, is formed in a plurality of sections of progressively increasing cross sectional area. By this means the velocity of the air currents in the several sections will vary, the velocity decreasing in proportion as the cross sectional area of the channel increases. All of the sections contain fingers or projections in the path of the air currents and against which the lint will be projected, and the force with which the lint is thus projected against the fingers will be varied in accordance with the variation of speed of the air currents as will be well understood.

The main object of this portion of my invention is to provide for a more severe action upon the fibers at the beginning of the cleaning and separating operation and at which time the fibers are in a matted condition, and to decrease the severity of such action as the fibers pass through the channel and become gradually separated.

My invention also consists in certain novel features of construction and combinations of parts including a novel arrangement of screens at the end of the channel sections, and receiving chambers to the rear thereof, all which will be fully pointed out hereinafter, and in order that my invention may be thoroughly understood, will now proceed to describe an apparatus constituting an embodiment of my invention, having reference to the accompanying drawings illustrating the same, and will then point out the novel features in claims.

In the drawings: Figure 1 is a view in side elevation of an apparatus embodying my invention, showing the same as receiving lint through a blower frame gin delivery. Fig. 2 is a View in central longitudinal section through the apparatus, showing the same upon a somewhat larger scale. Fig. 3 W5 is an end view thereof. Fig. 4 is a detail view in transverse section showing a set of the projections employed and the means for adjusting the degree of inclination thereof.

The apparatus includes a casing 5, here shown as of rectangular form. Within this casing is a channel 6 formed'in a plurality of horizontal superposed sections. These sections are formed by horizontal shelves or partitions 7, end deflecting plates 8 arranged obliquely to the said horizontal shelves or artitions, and end screens 9 which are a so arranged obliquely with respect to the horizontal shelves or partitions. The shelves or partitions 7 have openings 10 therethrough at one end to form a communication between contiguous channel sec tions, the openings 10 being arranged in alternate shelves or partitions at opposite ends thereof so that a channel of zigzag form results. The screen 9 is arranged at the forward end of each channel section while the oblique deflecting plate 8 is arranged at the rear end of the immediately succeeding channel. A lateral admission 11 is provided at one end of the lowermost channel section while theuppermost channel section is provided with an extension 12 which constitutes a discharge from the said channel. The. lateral inlet 11 is connected throu h a suitable pipe 13 with a blower 14, whi e the discharge 12 is connected with a suitable delivery pipe. 15 as appears. in Fig. 1. The blower 14 receives the lint to be treated from a gin 6 or other source of supply.

At the rear of the oblique de ecting plates 8 and the oblique screens 9, and between the same and the end cas' walls at both ends of the apparatus are c ambers 17 such as constitute receiving chambers for the delivery of material which passes through the screens 9. The chamber 17 in its entirety is broken up into smaller chambers by means of a series of swinging doors 18 which extend from the various oblique screens to the angle plates immediately beneath them. These doors may be opened and closed by means of handles 19 at the exterior of the casing so that the contents of the individual inclosures may be deflected in the common chamber at will. This common chamber has a discharge opening 20 at the bottom thereof, the apparatus in Fig. 1 being shown as provided with sliding drawers 21 in communication therewith.

Located in each of the channel sections are sets of obliquely disposed fingers or projections 22. In the form shown these projections are in the form of small cylindrical rods or pins 23 (see Fig. 4:), the same being mounted upon a transverse rod 24 which is mounted in the casing. This rod extends through the casing walls and is provided on the end with an arm 25 which carries a handle 26, the latter forming a means by which the device 22, as a whole, may be angularly adjusted, and by which through the interlocking engagement thereof with notches 27, the same may be held in its adjusted position.

In operation lint is drawn from the gin 16 or other source of supply by means of the blower Hand is delivered through the pipe 13 to the channel 6. It enters the channel 6 through the admission 11 at the righthand end of the channel 6 (see Fig. 2). Thence the air currents carrying the lint pass through the lowermost channel section around the end thereof through the opening 10 into the next succeeding channel section, and so on throughout the apparatus. In passing along in one channel section the lint is caught by the fingers or other projections 22, the fibers being opened out during this action, separated and cleaned. When the fibers reach the end of any channel section they strike the inclined screen 9, and in rubbing across the screen are further relieved of dust, dirt, leafy trash, etc., carried with it. Moreover the dust which was separated from the fibers in the action thereon when they wereheld by the fingers, is also blown up to the screen and passes therethrough.

As the air currents carrying the lint pass from one channel section to the other, the increased cross-sectional area of the succeeding channel sections will cause a'decrease of rate of the flow. By this means the action in the lowermost channel section where the lint is in its most compressed condition, may be quite violent, while this action will progressively decrease until it is quite delicate in the uppermost section. This is exceedingly desirable in the operation of the apparatus as it results in the reatest efliciency of action. As the dirt an dust collects in the various individual compartments at the ends of the channels the individual doors 18 may be opened and the material dumped therefrom into the common chamber 17, thence into openings 20 into the receiving drawers 21. This may be done from time to time as is found necessary or desirable, the doors thereafter being closed in order to prevent the air currents of higher tension in the lowermost channel section from being short circuited through the chamber 17 into the upper channel sections, and also to prevent the fibers from clinging to the screens.

Suitable openings or windows 28 may be provided in various points throughoutthe apparatus for purposes of inspection, and if they be constructed so that they will open, (as they may if desired) for the purpose of accessibility; and in order to prevent clogging of the apparatus at the bases of the sets of fingers, I have provided oblique guard or guide plates 29 which will direct the fibers away from the bases of the fingers, on to the parts thereof constructed to receive them.
